Seems to me I read somewhere there is a fixed (?) amount of time a hole can be expected to produce - was it 20, or 30 days (?) from when tapped?
I seem to recall this as the amount of time before all the cells are 'healed' (closed off) - ????
Does anyone out there have information on this?
- Do the freezing temps extend this time? If so, is it that all the time below freezing does not 'count'?
- Do the 'check valve' taps extend this time? If so, how much?
- Do the vacuum systems extend this time?
With what looks like to be a drawn out season here in Aitkin County (just got 12" of snow and high temps in the low 30's forecast for the next week) ---- just wondering about the merits, if any, of delaying tapping.
